feat: Add Kinesis lambda event support to Parser utility #226

This adds automatic base64 decode in the schema.

Awesome, looks clean enough and specially the pre-validation piece :)

One additional ask as with other PRs:

1. Could you please update the model and envelope docs?

https://github.com/awslabs/aws-lambda-powertools-python/blob/develop/docs/content/utilities/parser.mdx#extending-built-in-models

https://github.com/awslabs/aws-lambda-powertools-python/blob/develop/docs/content/utilities/parser.mdx#built-in-envelopes

Adding additional comments to commit later on renaming Kinesis with KinesisDataStream to allow expansion with other products

[heitorlessa]

thanks a lot as always @risenberg-cyberark - As discussed, I'll commit these suggestions, and will try pushing the docs to your branch then merge. Failing that, I'll merge as-is, then send another PR with docs and suggestions implemented ;)

ETA: This Friday EOD
